Thusalthoughthenotesinclude what was discussed in the lectures, in their detailed coverage they tend to focus These are directions suggested to students on how to prepare their lectures. The necessity to arrange the theory in a systematic way and to explain to the audience the various connections between the different results, often leads to new insights and, in consequence, to new results. From this, one sees that arithmetic facts about elliptic curves correspond to arithmetic facts about special values of modular functions and modular forms.
